title: [Urticarial vasculitis syndrome. A case report and review of the literature].
abstract: Urticarial vasculitis (UV) is a primary syndrome or a cutaneous vasculitic lesion occurring in the course of a collagen disease, as the systemic lupus erythematosus (LE). UV is a recently recognized disorder which affects most exclusively the female sex and may be differentiated from common (nonvasculitic) urticaria because it is characterized by inflammation and necrosis of blood vessels (vasculitis). UV and common urticaria may be induced by a variety of factors and pathogenetic mechanisms. It seems that a continuum exists, ranging from benign cutaneous lesions of urticaria to vasculitis with strong immunological involvement. On the basis of the clinical evaluation, two major groups of UV have been classified, the normocomplementemic, with a less severe clinical course, and the hypocomplementemic UV, a rare immune complex-mediated disorder related to LE as for as the similar pathogenesis and systemic involvement are concerned. A case of a young female patient with a unique syndrome characterized by crises of urticarial recurrent painful lesions of unknown origin, associated with angioedema of the tongue and soft palate, severe malaise, arthralgias and abdominal pain is reported. Dyspnea and cough were sometimes present, but fever was absent. Symptoms were caused by physical stress, heat or pressure and were little responsive to corticosteroids. Although skin biopsy did not prove with certainty the occurrence of vasculitis, clinical data and laboratory findings (normal levels of complement fractions, raised erythrocyte sedimentation rate, presence of cryoglobulins and ASMA, nDNA and AMA autoantibodies and absence of ANA autoantibodies and LE cells) suggest a normocomplementemic UV, excluding a classic LE. The family doctors and the internist must become familiar with the "lupus-like" syndromes, which include UV. In fact, a correct diagnosis of this syndrome is important because, although prognosis of UV may not be severe, the possibility exists of a systemic involvement (mainly renal) with progression to LE.
